My two wiener dogs got into my sons a&d diaper ointment and ingested a small amount. Is this poisonous to them?

I wouldn't worry that much about it. A&D is basically petroleum jelly. If anything they may get the squirts. It does say if accidental ingestion occurs drink water and do not induce vomiting. But it wouldn't hurt to call the ASPCA Poinson hotline (888) 426-4435
